In the color-concept association task, participants were presented with a concept word at the top of the screen (sunshine or shade) and a colored square centered below (Fig. REF A). They rated how much they associated the given concept with the given color by moving a slider along a scale ranging from “not at all” (\(-200\) ) to “very much” (200), and clicking “continue” to begin the next trial. Each concept was rated for each of the UW-71 colors [1]} shown in Fig. REF B (see Table REF  in Supplementary Material for CIELAB coordinates). The UW-71 colors include 58 colors uniformly sampled from CIELAB space (UW-58 from [2]}, [3]}), plus 13 additional colors sampled at a higher lightness plane to incorporate more saturated yellows and greens [1]}.
